Question

What are the 3 posulates of bhor's model of an atom?​

Answer 1

• According to Bohr's Model of an atom, Electrons revolve around the nucleus in different orbits or shells like K-Shell, L-Shell, M-Shell e.t.c

• As long as Electrons revolve around a particular orbit they can neither gain energy nor loose energy. Such orbits are called as Stationary orbits and these orbits don't take part in a chemical reaction.

• It explains the stability of an atom and also line spectrum of a hydrogen atom.

• Negatively charged Electrons revolve around the nucleus which is present at the center of the atom.

Answer 2

Answer:

postulates of Bohr's atomic model :

According to Bohr's theory , electrons revolve in definite circular orbits around the nucleus and these orbits are designated by the letters K, L, M, N or by the numbers 1, 2 ,3, 4 and so on.

As long as the electrons revolve in a particular orbit they can neither gain energy nor loose energy. Such orbits are called as stationary orbits or stationary states.

When an electron jumps from an higher orbit to a lower orbit it releases energy in the form of radiations and when an electron jumps from lower orbit to a higher orbit it absorbs energy in the form of radiations.

The angular momentum of an electron is an integral multiple of h/ 2π mvr = nh/ 2π

It explains the stability of an atom and also the line spectrum of hydrogen atom
